2014 Nissan Leaf named overall cleanest car in US

A research firm has named the zero-emission 2014 Nissan Leaf the cleanest production vehicle in the US, and that's figuring in the full, wheel-to-well lifetime impact of the car on the environment. The Automotive Science Group (ASG) studied more than 1,300 automobiles with at least four seats across nine categories, measuring everything from the amount of fuel needed to run the car during its lifetime to the extraction of natural resources to build the thing in the first place to end-of-life processing. ASG calls the process "wildly complex." The battery-electric Leaf, with its 84-mile single-charge range, took top honors overall, but there were other highly ranked vehicles in different categories. ASG also said that the Mitsubishi Mirage, with its sub-2,000-pound curb weight and 40 miles per gallon fuel economy, was the cleanest among gas-powered vehicles, while the Chevrolet Spark had the lowest cast of ownership over five years. Last month, the American Council for an Energy-Efficient Economy (ACEEE) put together its annual "Greenest" and "Meanest" (notice: we didn't say "Cleanest") lists and put the Leaf at number three. Topping that list was the Smart ForTwo ED battery-electric, but that was followed up by the Toyota Prius C compact hybrid, so fans of those vehicles can now start a healthy debate. The ACEEE uses data from the Environmental Protection Agency and California Air Resources Board to compile its list. We have ASG's press release below. Life-cycle Assessment of 1,300 Models Reveals Best of 2014 FOR IMMEDIATE RELEASE 4 February 2014 [Santa Rosa, CA] – The Automotive Science Group (ASG) conducted a comprehensive life-cycle assessment of over 1,300 automobiles across nine categories to distinguish the BEST model year 2014 vehicles in environmental, economic, social and "all-around" performance. Auto consumers are now equipped with a car buying guide founded on principled facts, a departure from the notoriously subjective test drive "editor reviews" that have long been the industry norm. Using a unique combination of vehicle data inputs that include conventional specifications as well as ground-breaking social, environmental and economic performance indicators, ASG's back-end algorithms are wildly complex, but the front-end results – meaningful vehicle ratings and distinguished awards – are forthright and consumer-friendly. ASG's Automotive Performance Index is for automotive consumers what Google is for web users.

2016 Nissan Titan XD arrives with diesel V8 power

Feels like this one's been coming soon (or is that #CumminsSoon?), forever. Over a decade since the Nissan Titan launched, the Japanese fullsize pickup has finally been given a full redesign, and it looks to be a worthy – and interesting – competitor in the light-duty pickup class. First and foremost, the truck debuting here in Detroit is the Titan XD – it's not a trim level, but a totally different version of the standard Titan, despite looking the same. The best way to explain the difference is that if the Titan competes with a Silverado 1500, the XD competes with something a step higher, but not a full 2500. Think of it as a Silverado 2000 or something – a step between light and heavy duty. Nissan truly thinks there's a white space in this pickup segment. The company isn't ready to release details on the standard Titan just yet, and the XD with the diesel engine will be the first version to come to market. The diesel in question is the long-awaited 5.0-liter V8 from Cummins, producing 310 horsepower and 555 pound-feet of torque, mated to a six-speed automatic transmission. When properly equipped, the Titan XD can tow up to 12,000 pounds, and has a payload capacity of 2,000 pounds. Nissan has confirmed that gasoline V6 and V8 options will be available on both Titan and Titan XD models, but has not released any details at this time. The 5.0-liter Cummins turbodiesel V8 will only be offered on the XD. Nissan is upgrading its Around View Monitor with features to aid with towing, too. Shown here as a Crew Cab, the Titan will be offered in King Cab and Single Cab configurations, as well, with three bed lengths (a 6.5-foot bed is seen here). Nissan has also told us that a lower-grade work truck will be available, as well. As the models roll out, the Titan and Titan XD will be offered in several trims, including a rugged-looking Pro-4X model and a new, top-of-the-line Platinum Reserve. All except the Pro-4X can be had with two- or four-wheel drive. Speaking of looks, we have to say, this is a pretty nice looking truck. Its appearance is fresh and modern, if awfully reminiscent of other trucks in the segment (hard to offer a unique design with that shape, of course). Up front, there are premium elements like available LED headlamps with LED running lamps, and out back, those same modern bulbs are used for the taillamps.

IIHS: High numbers of drivers treat partially automated cars as fully self-driving

WASHINGTON — Drivers using advanced driver assistance systems like Tesla Autopilot or General Motors Super Cruise often treat their vehicles as fully self-driving despite warnings, a new study has found. The Insurance Institute for Highway Safety (IIHS), an industry funded group that prods automakers to make safer vehicles, said on Tuesday a survey found regular users of Super Cruise, Nissan/Infiniti ProPILOT Assist and Tesla Autopilot "said they were more likely to perform non-driving-related activities like eating or texting while using their partial automation systems than while driving unassisted." The IIHS study of 600 active users found 53% of Super Cruise, 42% of Autopilot and 12% of ProPILOT Assist owners "said that they were comfortable treating their vehicles as fully self-driving." About 40% of users of Autopilot and Super Cruise — two systems with lockout features for failing to pay attention — reported systems had at some point switched off while they were driving and would not reactivate. "The big-picture message here is that the early adopters of these systems still have a poor understanding of the technologyÂ’s limits," said IIHS President David Harkey. The study comes as the National Highway Traffic Safety Administration (NHTSA) is scrutinizing Autopilot crashes. Since 2016, the NHTSA has opened 37 special investigations involving 18 deaths in crashes involving Tesla vehicles and where systems like Autopilot were suspected of use. Tesla did not respond to requests for comment. Tesla says Autopilot does not make vehicles autonomous and is intended for use with a fully attentive driver who is prepared to take over. GM, which in August said owners could use Super Cruise on 400,000 miles (643,740 km) of North American roads and plans to offer Super Cruise on 22 models by the end of 2023, did not immediately comment. IIHS said advertisements for Super Cruise focus on hands-free capabilities while Autopilot evokes the name used in passenger airplanes and "implies TeslaÂ’s system is more capable than it really is." IIHS in contrast noted ProPILOT Assist "suggests that itÂ’s an assistance feature, rather than a replacement for the driver." NHTSA and automakers say none of the systems make vehicles autonomous. Nissan said its name "is clearly communicating ProPILOT Assist as a system to aid the driver, and it requires hands-on operation.
